In Feb of 06 we bought a KDSR60XBR1, and were thrilled with the picture quality! In Nov, I started to notice a yellow line on the right side of the picture from the top to the bottom. We had a local Sony repair centre look at it, and sure enough he stated it needed a new OB.
The part was on back order here in Canada for at least 6 weeks, and Sony wanted me to wait...
